Open diff and rear sway bar

[HKSZ]

Hi all I'm autocrossing a standard 280zx with standard open 3.7 diff this weekend on dirt and wonder if i should take off the rear sway bar, had a chance to run it last week it went well but tended to spin me out on transitioning from right to left turns.

My 240z handles brilliantly with a small fr bar no rear bar and a LSD.

I'm Just trying the big 280zx for fun but still want to be competitive

You can try disconnecting one side of the swaybar to see what it feels like.

A LSD will be a big improvement, but it's a big expense just for "fun".

I would imagine that autocrossing a 280ZX would probably be a similar experience to when I autocrossed my 810........

Or slightly better than my Honda Ridgeline.

ahh where's the love for the 280zx, 4w discs, power steering, fuel injection.

Our autox is like a dirt rallysprint over 1 or 2 kms. I ran a $400 280zx years ago and embarrassed alot of rally prepped cars in the over 2lt class.

If disconnecting one end of the sway stops it from working I'll give it a go, not sure if I need to modify car or driving style with an open diff. thanks

Just disconnect one end link and try that but now that you've added the fact that the AX course is mostly dirt, then my Ridgeline comment makes even more sense.

It becomes a matter of personal opinion.

The early 240z was a purist sports car. By the time the 280zx came out, the federal government had changed the rules, forcing certain things. Then Nissan added to many creature comforts and it went from purist to luxo-boat.

update and i found it best to leave the bar connected on the 280zx, better to live with the oversteer than the twitchy cornering without a bar.

No bar or a open diff in the 240z has never been a big issue for me, perhaps its the design and weight of the 280zx rear suspension( similar to a 510).

Dropped 2 sec a lap in a car I hadn't driven before but still 5 sec down on what I did in the 240z the year before
